Create Disk File

1. Change the maximum resolutions xRes and yRes to smaller values, if necessary.

2. Input x, y, and Size. x and y are Cartesian coordinates with (0,0) being lower left corner of viewer.
Size is the radius of the disk as measured from (x,y). Input the color values Red, Green and Blue in the range [0,1].
Select Filter and Operation using the drop-down selections.

Start Over

Starts a new Session. I still have to manually delete files off the server for now though.

Notes:

These are somewhat random and at a later date should be organized

1. The DV 557 was tested on three Windows PC laptops, one Mac laptop and my Ubuntu desk top. I do not have the exact configurations
of this machines. To get the most machines to work, a lot of experimenting with various embed and object tags was done
to get the right combination of of those tags.

The Mac was most finicky about its embed and object tags. The Mac would not play its own .MOV or .AVI movies
The Windows and Ubuntu systems were more flexible. In other words, the Mac would not always play movies that
were embed or objects of MicroSoft or opensouce players such as the AVL player. But Microsoft and Unbuntu played
the Quicktime embeds and objects. So most of the movies have Quicktime embed and objects in an attempt to make the Macs play more
of the movies. Sometime the Mac would not play MOV files or the AVIs.
The Ubuntu machines plays nicely with Macs and Windows. They play more consistently any of the movie formats, AVI, FLASH
MOV and MPG

When a Windows machine fails to play a quicktime AVI, it claims you need a Quicktime plugin. But I have not found that to be true. You will go in a circle looking for plugins and reinstalling Quicktime

Ubuntu plays the AVIs but will not loop. Plays once and quits. Macs will not play .AVI or .MOV. Windows will not play .AVI but will play .MOV

Ubuntu plays all the movies better and consistently the Mac or Windows. It may stall on MPGs
and plays the movies too fast to see depending on the disk file size.

Ubuntu will play Flash but the conversion from MPG to FLV probably requires experimenting with the frame
rate. The file size may have something to do with the speed at with images play in the various players.

I have run DV 557 from wireless machines, Windows and Macs including the Macs in Hodges Library
But running DV 557 on EECS's Ubuntu lab machines gives the best results. Those machines play all the image formats.

2. There was a lot of very interesting program interfacing

C - All of that code was written

PHP - I was more familiar with PHP than CGI. I did run into the permission issues

Php built command files containing ffmeg and convert commands to convert to various image format wrote them to my area
and then ran the command file

JavaScript - Handled the client side such as adding and deleting rows from forms

ffmeg - There are so many options for conversions. I only used the plain and simple. So
the movies are played (avi, mov, mpg flv) they may go too fast, their color may be off or pixelization occurs

HTML - Not programming but still interesting when combined with everything else
